Venturi for Heat Transfer - Heat pumps consume power in order to transfer heat from a source to a higher-temperature sink. This invention enables spontaneous heat transfer from a heat source to a small portion of the generally warmer working fluid that is cooled locally by the Bernoulli effect to a temperature below that of the heat source. The Bernoulli effect occurs in a Venturi shaped duct shaped to maintain attached flow. Heat-transfer efficiency is improved by restriction of the heat transfer to a small portion of the Venturi in which the flow temperature, velocity, pressure gradient and the Nusselt effect enhance heat transfer. Within this region, heat transfer is maximized by a thermally conducting grid extending across the Venturi neck.
